具体实施方式
在下述的描述中，出于说明的目的，为了提供对一个或者多个实施方式的全面理解，阐述了许多具体细节。然而，很明显，也可以在没有这些具体细节的情况下实现这些实施方式。
为了更清楚地说明本发明，下面结合优选实施例和附图对本发明做进一步的说明。附图中相似的部件以相同的附图标记进行表示。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本发明的保护范围。
鉴于目前现有技术中柔性电路板主要是通过与扬声器外壳胶体粘合的方式固定，这种固定方式虽然能够在一定程度上抑制柔性电路板的振动，但是也存在着明显的缺陷：随着时间的推移，柔性电路板与扬声器外壳之间的胶体容易发生开裂，使得柔性电路板与扬声器外壳粘合失效，无法对柔性电路板进行有效固定。本发明提供一种扬声器，使柔性电路板与扬声器外壳更紧密地结合，避免柔性电路板的翘起，将柔性电路板有效固定，使其始终保持目标形态，且减少安装工作量，使安装工作更为便利。
具体地，结合附图进行详细说明，图1示出本发明提供扬声器的结构俯视图；图2示出图1的A部的放大图；图3示出本发明提供扬声器的结构主视图；图4示出本发明提供扬声器的立体示意图。
在本发明中的一种优选的实施方式中，所述扬声器包括形成有容纳腔的壳体，及收容在所述容纳腔内的振动***和磁路***；所述振动***包括有振膜以及与所述振膜结合固定的音圈；所述音圈连接有柔性电路板，该柔性电路板包括有延伸至壳体外的延伸部；所述壳体侧壁的外表面上包括有用于将所述柔性电路板延伸部与壳体侧壁的外表面固定的固定件，所述固定件包括有贯穿所述固定件上下两侧表面的容纳部，所述柔性电路板延伸部穿过所述容纳部，延伸部的端部由所述固定件内穿出。进一步地，此扬声器可以是扬声器单体，也可以为一体化的扬声器模组，本发明对此不做限制，下面以扬声器模组为例为本发明的扬声器进行详细的阐述。
结合图1至图4共同所示，一种扬声器模组，该扬声器模组包括形成有容纳腔的壳体1，及收容在所述容纳腔内的振动***和磁路***，在这种实施方式中，壳体1可以包括结合固定在一起共同围成所述容纳腔的上壳11以及下壳12。所述振动***包括有振膜以及与所述振膜结合固定的音圈，所述音圈连接有柔性电路板，通过柔性电路板实现与外部电路的连接。该柔性电路板包括有延伸至壳体外的延伸部2。所述壳体1侧壁的外表面上包括有用于将所述柔性电路板延伸部2与壳体1侧壁的外表面固定的固定件3，所述固定件3包括有贯穿所述固定件上下两侧表面的容纳部4，所述柔性电路板延伸部2穿过所述容纳部4，延伸部2的端部由所述固定件3内穿出。本优选的实施方式提供的结构方式使柔性电路板与扬声器外壳1更紧密地结合，避免柔性电路板的翘起，将柔性电路板有效固定，使其始终保持目标形态，同时，本实施方式中所述柔性电路板延伸部2穿过所述容纳部4，延伸部2的端部由所述固定件3内穿出，相比于现有技术而言，减少了大量的涂胶粘接工作，减少 安装工作量，使安装工作更为便利；进一步地，为加快生产效率，减少装配零件，所述固定件3为通过注塑的方式一体成型于所述扬声器的壳体1上。
在上述实施方式的基础上，优选地的方案是，所述固定件3至少包括有位于柔性电路板延伸部2两侧的呈相对设置的第一固定台31和第二固定台32，所述第一固定台31和第二固定台32上分别开设有第一固定槽311和第二固定槽321；；所述扬声器还包括有插板5，所述插板5位于所述柔性电路板延伸部2的外侧，且所述插板5的两端部分别***所述第一固定槽311内和第二固定槽321内固定；所述第一固定台31、第二固定台32、壳体1侧壁以及插板5之间形成所述容纳部4。本优选的实施方式提供的扬声器中设置有插板5，可以在进一步固定柔性线路板的同时，也便于当柔性电路板需要更换或偏离目标形态时，方便拆卸柔性电路板或者调整柔性电路板的形态。
另外，在一些优选的实施方式中，所述第一固定槽311贯穿所述第一固定台31的顶面，所述第二固定槽321贯穿所述第二固定台32的顶面，通常情况下，所述第一固定槽311、第二固定槽321不贯穿第一固定台311、第二固定台321底面，因为当插板5***到所述第一固定槽311、第二固定槽321内固定时，容易引起插板5脱落。但是本领域技术人员应当理解的是，当插板5与所述第一固定槽311、第二固定槽321之间存在过盈装配时，为了可以更加方便的安装和拆卸插板5，第一固定槽311、第二固定槽321也可以设置成为贯穿第一固定台31、第二固定台32底面的形态。本发明仅提供一种适用于现有扬声器模组结构的最优的技术方案，但并非用于限制。
为了实现所述柔性电路板有效固定，使其始终保持目标形态，本发明还提供另外一种优选的实施方式，即所述固定件至少包括有位于柔性电路板延伸部两侧的呈相对设置的第一固定台和第二固定台；所述第一固定台包括有由壳体侧壁的外表面延伸出的第一固定部以及由第一固定部的端部向第二固定台方向弯折形成的第一弯折部；所述第二固定台包括有由壳体侧壁的外表面延伸出的第二固定部以及由第二固定部的端部向第一固定台方向弯折形成的第二弯折部；所述第一固定台、第二固定台、第一弯折部、第二弯折部以及壳体侧壁之间形成所述容纳部。进一步地优选地，所述第一弯折部与壳体侧壁的距离不大于所述柔性电路板的厚度，所述第二弯折部与壳体侧壁的距离不大于所述柔性电路板的厚度，进一步地，为确保柔性电路板与外壳侧壁更好地固定，所述第一弯折部端部与所述第二弯折部端部之间的距离不大于所述柔性电路板延伸部的宽度。
为达到本发明的目的，本发明还提供了另一种优选的实施方式，即所述第一弯折部与第二弯折部连接成一体形成连接壁；所述壳体侧壁、第一固定台、第二固定台与连接壁之间形成所述容纳部。这种结构可以有效防止插板在外界摩擦力的作用下造成松动或脱落，影响对柔性电路板的固定。
需要说明的是，所述固定件形成于所述上壳侧壁的外表面上，或者形成于所述下壳侧壁的外表面上，本发明对此不作限制。如图3所示所述第一固定台31和第二固定台32形成于所述上壳11侧壁的外表面上，且所述第一固定台31的顶面以及第二固定台32的顶面与所述上壳11的顶面齐平。目的在于确保柔性电路板延伸部2直接进入所述第一固定台31与第二固定台32之间形成的容纳部4内，进一步从左右方向固定柔性电路板延伸部2，减少柔性电路板延伸部2悬空的长度，避免柔性电路板延伸部2在使用过程中出现线路不稳定，容易串线的问题，从而无法对柔性电路板进行有效的固定，同时此结构方式保持扬声器底部的平整美观，易于装配。
上述实施方式是以扬声器模组为例进行的详细阐述，当为扬声器单体时，所述扬声器单体包括振动***和磁路***，部分扬声器单体会结合壳体以保护振动***。所述振动***包括有振膜以及与所述振膜结合固定的音圈，所述音圈连接有柔性电路板，该柔性电路板包括有延伸至壳体外的延伸部。所述壳体侧壁的外表面上包括有用于将所述柔性电路板延伸部与壳体侧壁的外表面固定的固定件。其固定件对柔性电路板和壳体侧壁的固定作用与上述实施方式中的基本相同，故在此不再赘述。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本发明的技术方案所引伸出的显而易见的变化或变动仍处于本发明的保护范围之列。
